This invention relates to a novel nozzle packer, by means of which the space between a nozzle and a iiller pipe is packed off while a liquid is being admittedv to the stock tank thru the ller 5 plpe.

An object of my invention is to provide a novel nozzle packer which will effectively pack off the space between the nozzle and diierent sized filler pipes.

' Still another object is to provide a novel nozzle packer which can be quickly and easily attached to the nozzle and which can be so arranged as to quickly pack oi around the nozzle.

Still another object is to provide a nozzle packer of the character stated, which is simple in construction and inexpensive to manufacture.

Other objects, advantages and features of invention may appear from the accompanying drawing, the. subjoined detailed description and the appended claim.

In the drawing Figure 1 is a longitudinal sectional view of the packer mounted on a nozzle, showing one method of packing oi around the nozzle.

Figure 2 is a. View similar to Fig. 1, showing another method of packing off the nozzle.

Figure 3 is a view similar to Fig. 1, showing still another method of packing oi the nozzle, with the same packer as illustrated in Fig. 1.

Figure 4 is a view similar to Fig. 1, showing a fourth way of packing oft' around the nozzle.

Figure 5 is a view similar to Fig. 1, showing a fth way in which the packer can pack: off around the nozzle.

Referring more particularly to the drawing, the numeral I indicates a nozzle which is attached by means of the usual hose 2 toI a tank truck, or the like, from which the liquid is drawn and deposited in the stock tank, such as in a gasoline 40 service station, or the like.

The iiller pipe 3 extends into the stock tank (not shown). These ller pipes are of different diameters and, consequently, there is an annular space between the nozzle I and the pipe 3 which 5 must be packed off in order that the liquid may flow quickly from the truck into the stock tank.

For the purpose of packing oi the space between the nozzle and the pipe, I provide a packer 4. The packer is made entirely of iiexible material, such as rubber, and consists of a sleeve 5 which tightly grips the nozzle I. The walls of the sleeve are relatively thin, so that the sleeve 5 can be pulled outwardly and fitted over the pipe- 3, as shown at 6, in Fig. 2. If the diameters of the nozzle I and the pipe 3 are approximately the same, then the lower end of the sleeve 5 may butt against the top of the pipe, as shown in 10 Fig. 1. If it is desired to have a somewhat thicker wall at the bottom in order to pack oi a somewhat larger pipe, the sleeve 5 can be bent back upon itself, as shown at 'I in Fig. 4.

A cup-8 is integrally formed on one end of the 15 sleeve 5, and the walls of this cup are somewhat thicker than the sleeve 5 so that the cup will at all times retain its shape. The cup flares outwardly, as shown, and the outer surface of this cup may be corrugated as shown at 9, for the 2o purpose of strengthening the walls of the cup-, and also to more effectively t the pipe 3.

If the pipe 3 is quite large in diameter, the nozzle I may be dropped into the pipe to a point where the cup 8 fits into the pipe, as shown in 25 Fig. 3. If desired, the packerrmay be reversed, with the cup 8 extending downwardly, and then the inside of the cup fits over the outside of the pipe 3, as shown in Fig. 5.

The sleeve 5, as previously stated, tightly grips 30 the nozzle I and no other holding means is necessary.

Also, with my arrangement, the packer can easily be removed from the nozzle and reversed for the purpose of using it as shown in Fig. 5.

Also, the packer can be moved longitudinally of the nozzle to suit varying conditions.

Having described my invention, I claim:

A nozzle packer adapted to be mounted on a ller nozzle comprising a sleeve tightly gripping the nozzle, a cup integrally formed with the sleeve, said cup and sleeve Ybeing formed of rubber, the walls of said sleeve being relatively thin, the walls of said cup being relatively thick, and the outer surface of said cup being corrugated.
